(A) Let the rate law be $r = k[A]^x[B]^y$.Comparing experiment $(3)$ and $(1)$:$\frac{0.10}{0.10} = \frac{k[0.024]^x [0.035]^y}{k[0.012]^x [0.035]^y}$$1 = (2)^x \implies x = 0$.Comparing experiment $(2)$ and $(3)$:$\frac{0.80}{0.10} = \frac{k[0.024]^x [0.070]^y}{k[0.024]^x [0.035]^y}$$8 = (2)^y \implies y = 3$.Therefore,the rate law is $Rate = k[A]^0[B]^3 = k[B]^3$.

Which one of the following statements is wrong?

Easy

View Solution

The mechanism of the reaction $2NO_{(g)} + Br_{2(g)} \rightarrow 2NOBr_{(g)}$ is given by:
$1) NO_{(g)} + Br_{2(g)} \rightleftharpoons NOBr_{2(g)}$ (fast)
$2) NOBr_{2(g)} + NO_{(g)} \rightarrow 2NOBr_{(g)}$ (slow)
If the second step is the rate-determining step,what is the order of the reaction with respect to $NO_{(g)}$?
